I've used some rolls of this film and had pretty bad results most of the time: the film grain is huge and film looks underexposed, even though I'm using shutter speeds recommended by the camera (Konica Hexar), which are well within the camera's maximum shutter speed. At first I thought it might be the lab, but I've tried at least two different ones with the same result. So could it be the film? I've read that Press 800 might be better, though I do not remember getting results that are very much better. Has anyone tried the new Natura 1600 film?
